IPV6 statics and IP SLA

Question

Hi,
I have a test setup working fine in general with IPV4/IPV6. However, I have one situation where I'd like to do what I do in IPV4 for IPV6
The situation is where an IPV4 SLA pings two IP addresses. Then there are two static routes tracking these two routes. Under certain failure conditions, the tested destinations disappear and the pings fail. The static routes disappear and a floating static on another router seen via OSPF takes over.
All this works well with IPV4.
I'd like to do the same in IPV6 but there is no equivalent to the
ip route x.x.x.x y.y.y.y z.z.z.z track N command
I have 12.4.22T and can configure the icmp echo tests fine and they go up/down correctly when the tested destination goes, but I can't configure the ipv6 static as there is no command:
ipv6 route x:x:x:x::/x z:z:z:z::z track N
Had a look round 15.2 code and still nothing.
Anyone know if this is coming ?
Or is there another way ?

Answered my own question. Found a link on a non-Cisco forum that said IPV6 static route track not yet there although on the list and referred to EEM as alternative.
So this is what I did - and it all works correctly.
#On c7200-adventerprisek9-mz.124-22.T4.bin
#First create tests that check the availability of something known via BGP.
#If BGP peering fails this goes away.
#There are two tests to BGP peer loopbacks for resilience
#since in this case there are two BGP peers
ip sla 3
icmp-echo FC00:1:11:115::1
timeout 1000
frequency 5
ip sla schedule 3 life forever start-time now
ip sla 4
icmp-echo FC00:1:11:115::2
timeout 1000
frequency 5
ip sla schedule 4 life forever start-time now
#Then setup some trackers against the SLAs.
track 3 ip sla 3 reachability
delay down 2 up 2
track 4 ip sla 4 reachability
delay down 2 up 2
#then set up 2 'down' handlers and 2 'up' handlers. The handlers add static routes if the BGP peers
#are up. The handlers remove if they are down letting OSPF (in this case) deal with an alternate.
#a syslog is sent to show the handler action.
